Assignment B


Forum: The Importance of Oceans

After viewing the class Ocean lectures, as well as viewing the video: Earth the Biography: Oceans, think about how important oceans are. Pick an aspect that is particularly important to you and describe it. Discuss how you are thankful for something related to the ocean.


Instructor's example post: There are many ways that the ocean is important to us. Half of the earth's oxygen that we breathe comes from phytoplankton blooms in the oceans. We utilize many ocean resources such as salt, minerals, and food. But I think what I am most thankful about has to do with the opportunity for discovery: as a person who loves snorkeling and scuba diving I continue to be amazed by the beauty and diversity of lifeforms in the ocean. A few months ago I went sailing in Newport Bay with my family. My husband had taken sailing classes at Orange Coast Community College, and we rented one of their boats for the afternoon. As we were docking the boat in the evening (it had gotten completely dark), we noticed bright green flashes in the water just by the dock. My son scooped up some of the green material and shone his flashlight onto it: it was a worm! I had never seen that before. The area around the docks was swarming with these bio-luminescent creatures, leaving glowing trails behind them as they moved through the water (see picture). I never get tired of visiting the beach and watching the waves, shorebirds, whales....... I am thankful we live close enough to visit and see these amazing things.

What is it that you enjoy (or are thankful for) about the ocean?
